Good tester but very glitchy
I havent taken either test for A+ cert yet, but I do like this apps tester. However, its got some glitches. If a question has long answer choices, a graphical glitch prevents some (or in some cases ALL) of the final answer choice from being readable. Also, the quizzes on the objectives have no option to return you to the apps home screen - the only way to get to a different part of the app is to shut off the phone completely and reboot; simply exiting the app doesnt work because youll be put right back into the objectives when you go back into it.
